Subject: unique columns of a matrix
Dear all,
I have a matrix of repeating columns in R, for example a matrix X is
[,1] [,2] [,3] [,4]
[1,] 1 1 1 1
[2,] 1 1 2 2
I want to store unique columns of the matrix X in a new matrix Y.
Therefore, Y will be
[,1] [,2]
[1,] 1 1
[2,] 1 2
It will be really appreciated if you can provide me some function for
this job.
Thanks for your time and effort in advance,
Roman
